Synthetic aperture radar (SAR) interferometry is employed to obtain
topographic information. Owing to noise, interferometric information
has to be filtered. The wavelet transform can be employed to filter the
interferometric phase, maintaining the spatial resolution, but new
signal models have to be studied in this domain for further processing.
